Abstract

The invention relates to a gas jet expansion actuating system and a control method. The gas jet expansion actuating system comprises a booster, a pressure boosting control valve, a first storage cylinder, a second storage cylinder, a third storage cylinder, a reactor and a guide cylinder. The pressure boosting control valve is connected with the booster. A pressure boosting port of the first storage cylinder, a pressure boosting port of the second storage cylinder and a pressure boosting port of the third storage cylinder are connected with the pressure boosting control valve respectively. A liquid outlet of the first storage cylinder, a liquid outlet of the second storage cylinder and a liquid outlet of the third storage cylinder and the guide cylinder are connected with the reactor respectively. A first pressure valve is disposed between the first storage cylinder and the reactor. A second pressure valve is disposed between the second storage cylinder and the reactor. A third pressure valve is disposed between the third storage cylinder and the reactor. An actuating pressure valve is disposed between the guide cylinder and the reactor. An actuating pressure cavity is formed between the side wall, connected with the reactor, of the guide cylinder and a balance weight. An actuating medium is disposed in the first storage cylinder. Fuel A is disposed in the second storage cylinder. Fuel B is disposed in the third storage cylinder. The gas jet expansion actuating system has the advantages of being simple in structure, convenient to control and safe and reliable; and the control method has the advantages of being simple in process and high in precision.

Description

technical field [0001] The invention relates to an actuating device, in particular to an actuating system based on gas jet expansion work, and a control method of the actuating system. Background technique [0002] Using gas jet expansion to do work is a commonly used actuation technology. It is more common to use a high-pressure container as an energy storage device and use the gas pressure to release the direct actuation device, such as an air actuation device, a nitrogen actuation device, etc. This actuating device has the defects of large volume and high storage pressure. With the popularization and application of the concept of liquid-gas phase change, a new type of gas actuator has appeared in recent years. By selecting a suitable gas (such as carbon dioxide) as the actuating medium, it will be liquefied during the filling process and will be in a gas-liquid saturated state. Storage; when working, the actuating medium absorbs heat and undergoes a phase change, and ca...
